What is the slope?
What is the y-intercept?
What does the slope of the line shown by the points mean in the situation?
What does the y-intercept mean in the situation?
Answers
Answer:
The slope is 20 or 20/1The y-intercept is at (0,60)The slope of the line shows for every class, the cost of fees increases by $20 at the gymThe y-intercept means that before a member can sign up for a class, they must pay a flat, one-time fee of $60Step-by-step explanation:
the slope-intercept formula is y = mx + bm = slope which is rise/runfor the slope, there is a formula that uses any two coordinates that are on the graph
y2-y1/x2-x1b= y-intercept which is where the graph crosses the y-axis
Finding Slope:
the two coordinates that I will be choosing is (0,60) and (1,80)using the slope formula stated above, I will plug in my coordinates. It does not matter which coordinate you choose as #1 and which one as #2, you just need to make sure that you keep it consistent80-60/1-0 = 20/1 = 20 is the slopeFinding Y-Intercept:
If you look at the graph, there is a point that is on the y-axis which is at (0,60). This means that the y-intercept is at (0,60)Answer:
1. Slope = 20
2. y-intercept = 60
Step-by-step explanation:
The slope of the line is found by dividing the change in y by the change in x or "rise over run":
[tex]\implies \textsf{slope}\:(m)=\dfrac{\textsf{change in $y$}}{\textsf{change in $x$}}=\dfrac{80-60}{2-1}=\dfrac{20}{1}=20[/tex]
The slope of the line for the given situation is the fee per class. Therefore, there is a $20 fee for each class a customer at the gym attends.
-----------------------------------------------------------------------------------------------
The y-intercept is the y-value at the point at which the line intercepts the y-axis, so when x = 0.
From inspection of the given graph, y = 60 when x = 0.
[tex]\implies \textsf{$y$-intercept}=60[/tex]
The y-intercept of the line for the given situation is the membership fee for the gym. Therefore, the membership fee for the gym is $60.

2(-x - 5) = 12
Answers
2(-x - 5) = 12
Step 1 : Expand the bracket.
=> -2x - 10 = 12
Step 2 :Add both side by 10.
=> -2x - 10 + 10 = 12 + 10
=> -2x = 22
Step 3 : Divide both side by -2.
=> -2x : (-2) = 22 : (-2)
=> x = -11
Therefore, x = -11.
Answer:
x = - 11
Step-by-step explanation:
2(- x - 5) = 12 ( divide both sides by 2 )
- x - 5 = 6 ( add 5 to both sides )
- x = 11 ( multiply both sides by - 1 )
x = - 11

Essentially, the formula calculating area is equivalent to the product of the rectangle's length and breadth.For the given question.
David's kitchen is 60 square feet in size. The kitchen is six times the size of the living room.Thus,
Area of kitchen = 6 x area of the pantry
60 = 6 x area of the pantry
area of the pantry = 60 / 6 = 10 square feet.
Area of the pantry = length x breadth

Some doctors recommend that men drink 3 liters of water every day. there are approximately 29.6 milliliters in 1 fluid ounce. which measurement is closest to the number of fluid ounces in 3 liters? responses 89 fl oz 89 fl oz 10 fl oz 10 fl oz 101 fl oz 101 fl oz 33 fl oz 33 fl oz
Answers
The measurement closest to the number of fluid ounces there are in 3 liters is 101 fl oz.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
If there are approximately 29.6 milliliters in 1 fluid ounce, then divide 3 liters by 29.6 milliliters to get the amount of fluid ounces it has.
29.6 milliliters = 1 fluid ounce
3 liters = 3000 milliliters
3000 milliliters / 29.6 milliliters = 101 fluid ounce
Hence, 3 liters ≈ 101 fluid ounces.

What is Pythagorean Theorem?The Pythagorean Theorem states that the hypotenuse, or side opposite the right angle, of a right triangle, which is represented by the square, is equal to the sum of the squares on the legs of the triangle (or, in popular algebraic notation, a2 + b2 = c2).
Where is the Pythagorean theorem used?The following are some significant applications of the Pythagorean theorem in daily life: used in architecture and building, used to determine the shortest distance in two-dimensional navigation. used to measure how steep a mountain's or hill's slope is.
Let the other 2 sides of the triangle be named a and b
Given:- a = 15.5ft
b = 13.2ft
According to the Pythagorean Theorem, We know that
[tex]a^{2}+b^{2}=c^{2}[/tex]
By substituting the values of a and b we get
[tex]15.5^{2}+13.2^{2}=c^{2}[/tex]
[tex]c^{2}= 414.5\\c=\sqrt{414.5}\\ c=20.35[/tex]

Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the forms, the shape and size should remain the same.
Properties of Congruence
Reflexive Property: An angle is congruent to itself.
Symmetric Property: The order of congruence does not matter.
Transitive Property: If two angles are both congruent to a third angle, then the first two angles are also congruent.
Here, It is given that
Angle ZWY is congruent to angle XWY

The displacement of the item in one unit of time is the definition of velocity.The speed at which an object goes in one direction is known as its velocity. Speed may be used to calculate both the speed of the car traveling north on the major highway and the speed of the rocket bursting into space.So, calculate the final velocity as:
Formula: v = √u² + 2asWhere u is initial velocity, a is acceleration and s is displacement.Now, we know that:
u = 108 km/ha = 4 km/s²s = 50 kmInsert values in the formula and calculate as follows:
v = √u² + 2asv = √108² + 2(4)(50)v = √11,664 + 400v = √12,064v = 20000.022499991 m/sRounding off: v = 20000 m/s

Answers
The domain of the function f(x) = 3x is (b) All positive integers less than or equal to 4
How to determine the domain of the function?From the question, we have the following equation of the function that can be used in our computation:
f(x) = 3x
In this case, the notations are given as
x = Number of splits
f(x) = number of new roots in each split
From the question, we have
Splits = 4
This means that the maximum value of x is 4
The other values of x would be
x = 1, 2, 3, 4
This can be represented as
0 ≤ x ≤ 4
The interpretation of the above notation is all positive values less than or equal to 4

Explanation:
x = number of weeks
y = height of the plant (inches)
The first sentence of "plant is 4 inches tall on week 8" gives us the point (x,y) = (8,4)
The second sentence gives us the point (32,16)
To find the growth rate, compute the slope.
[tex](x_1,y_1) = (8,4) \text{ and } (x_2,y_2) = (32,16)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{16 - 4}{32 - 8}\\\\m = \frac{12}{24}\\\\m = \frac{1}{2}\\\\m = 0.5\\\\[/tex]
The slope of 0.5 means the plant grows 0.5 inches per week.
Put another way, the plant grows 1 inch per every 2 weeks.
-----------------
Another approach:
The plant goes from 4 inches to 16 inches. It has grown 16-4 = 12 inches over the timespan of 24 weeks (since 32-8 = 24).
So its growth rate is 12/24 = 0.5 inches per week.

a circular curve is to be constructed with a 225 ft radius and an interior angle of 55 degrees. the separation between the stakes along the arc is 50 ft. assuming the curve is laid out from point to point, what is the last deflection angle?
Answers
The curve is laid out from point to point, the last deflection angle of circular curve is 26.5°
In the given question we have,
Radius of circular curve (R) = 225 ft
intersection or central angle in circular curve (I or delta) = 55°
separtion between stakes alaong arc = 50 ft
Angle of deflection is measured from tangent at PC or PT to any point .
deflection angle formula
deflection angle = (Lc /L)(I/2)
where, Lc is long chord and L is lenth of arc , I is central angle
first we find out the value of Lc and L
using formula , R = Lc / 2sin(I/2)
Lc = 225× 2 sin(55°/2) = 208 ft
L = R × I ×π/180°
L = 225 × 3.14 ×55/180 = 215.8 ~ 216 ft
put all the vales in deflection angle formula we get ,
deflection angle= (208/216)(55°/2) = 26.48° ~ 26.5°
